Project Grant 2612481
- The National Science Foundation Division of Polar Programs awarded the University of Washington $377,363 on September 1, 2026, under the Polar Programs assistance listing (CFDA 47.078) to develop a new dating method for million-year-old Antarctic ice using cosmic-ray-produced isotopes. The project will measure aluminum-26 and beryllium-10 isotopes accumulated in ice cores retrieved by the NSF Center for Oldest Ice Exploration (COLDEX), which has obtained samples exceeding 6.5 million years in...
- This National Science Foundation (NSF) Division of Polar Programs Project Grant award provides $300,642 to Oregon State University to trace polar sediments using short-lived radioisotopes in 75 years of Arctic and Antarctic sediment cores. The goal is to systematically study Arctic and Antarctic sediment accretion rates in order to improve the tools used to track changes in sedimentation, thereby helping coastal managers and decision-makers understand how climate change is impacting polar...
- This Project Grant award, valued at $359,487, was provided by the National Science Foundation's Polar Programs (CFDA 47.078) to The Trustees of Princeton University. The funding will be used to develop advanced analytical methods for high-resolution chemical imaging and dating of ancient ice cores from Antarctica's Blue Ice Areas, which contain climate records spanning over 1 million years. Specifically, the project will utilize cryo-cell laser ablation inductively coupled plasma mass...
- This $254,639 Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), will fund research to advance paleoclimate reconstruction techniques using thin or disturbed ice core sections. The University of Washington will develop new instrumentation and data workflows at the National Science Foundation Ice Core Facility to investigate sub-centimeter chemical and physical variations in polar ice cores. Researchers will...
- This National Science Foundation Project Grant of $529,842 supports the development of a new ice core proxy technique to reconstruct past melt in Arctic ice cores and apply the technique to study past warm periods. The award was made under the Polar Programs federal grant program (CFDA 47.078) to Oregon State University on February 1, 2022 for completion by January 31, 2025. Specifically, the grantee will develop a new method using the xenon/nitrogen ratio to reconstruct surface melt intensity...
- This $109,690 Project Grant award from the National Science Foundation's Polar Research (CFDA 47.078) program will support a collaborative research project to obtain new ice cores from Antarctica and analyze them to improve understanding of galactic cosmic ray flux and the Holocene methane budget. The project will use measurements of in-situ cosmogenic carbon-14 in the ice cores to test the assumption of a constant galactic cosmic ray flux over time, which is crucial for studies of past solar...
- This four-year, $532,649 project grant from the National Science Foundation Division of Polar Programs supports research titled "Collaborative Research: Circum-Antarctic Processes from Archived Marine Sediment Cores." Funded through the NSF's Polar Programs (CFDA #47.078), the grant aims to analyze marine sediment cores housed at Oregon State University to examine glacial and oceanographic processes around Antarctica over the past 20,000 years. Led by three early-career women principal...
- This two-year, $249,851 project grant from the National Science Foundation Division of Polar Programs supports research to advance paleoclimate reconstruction techniques for thin or disturbed ice core sections. The University of Maine will collaborate with other institutions to test next generation measurement methods for resolving annual layers at sub-centimeter scales in ice cores. Researchers will integrate precisely co-registered electrical conductivity, hyperspectral imaging, laser ablation...
- The National Science Foundation Division of Polar Programs awarded Idaho State University $182,888 on August 1, 2026, under the Polar Programs assistance listing (CFDA 47.078) to reconstruct Holocene sea ice history in the Bering Sea over a five-thousand-year record. The research integrates geological, cultural, archaeological, and environmental evidence to understand sea ice dynamics and wildlife responses in the southern Bering Sea. Work includes sedimentary DNA analysis of new sediment...
- This three-year Project Grant from the National Science Foundation's (NSF) Polar Programs ($489,233) supports research into the last deglaciation period in Greenland. Oregon State University is the primary awardee and will work with sub-awardee University of Washington to strengthen understanding of this "mystery interval" through basic scientific exploration best conducted in polar regions, as outlined in the NSF's CFDA #47.078 program. Specifically, the awardees will conduct...
The National Science Foundation Division of Polar Programs awarded Oregon State University $446,705 on November 1, 2026, to develop the Bipolar Ice Core Chronology (BICC), a unified timescale synchronizing 14 Antarctic and 8 Greenland ice cores under the Polar Programs assistance listing (CFDA 47.078). The award funds construction of a synchronized chronological framework merging and updating four existing ice core dating frameworks that currently disagree by up to several thousand years. The project will compile and validate a large database of volcanic eruptions recorded in ice cores and use volcanic synchronization to align timescales across both polar regions. The resulting open-source tools and datasets will enable worldwide research discoveries by improving dating accuracy and consistency for high-resolution environmental records including atmospheric gas concentrations, aerosols, chemistry, and regional temperatures captured in polar ice. Work is performed in Corvallis, Oregon, with a period of performance through October 31, 2029. The award supports one graduate student at Oregon State University and one undergraduate student for an REU summer internship, contributing to domestic STEM workforce development. The project increases scientific returns on prior U.S. investment in polar ice core collection and ensures the continued relevance of existing U.S.-drilled ice cores. Dating will address the Holocene (less than 11.7 thousand years before present) via bipolar annual layer counting of volcanically-synchronized records.
